Most devices that you would use to measure variables in the field (atmospherics and range) can be configured to output in imperial units. Worse case scenario, you may have to convert. This is no problem because the TI Voyage is powerful graphing calculator with the ability to perform conversions easily.

MOBALL does not output tables (range cards). It outputs sight adjustments only for the range you specify. There are many PC programs that output tables that you can print from your computer. MOBALL is intended to accept the specific field variables that are present for a particular shot, and calculate a custom solution for that shot only.
